I get a lot of mail from obviously unbalanced people. Enough in fact, that I've often wondered if there was a institution that allowed their patients to only read Slashdot. We've even had a few visits from some questionable individuals. A man who tried to bribe me with a car if I let him "reverse engineer" Rob Malda's Life comes to mind. He insisted on Rob being present for the process and couldn't explain to me what it entailed, so I suggested he leave. The personal visits are rare, however, compared to the amount of mail I get. Here are a few of my favorites; let's hope these people have started to take their medication. Read below and don't be worried if you don't understand all of it.

Chad_Wollenberg writes "Anyone who has used a derivative of Unix over the past 20 years has used Bash, which stands for Borne Again Shell. The geek in all of us makes us want to extend our ability to rule the command line. To truly master a Unix environment, you need to know a shell, and Bash is easily the most popular of them. Any Unix/Linux/BSD administrator knows the power at your fingertips is fully extended by what you can do within the Bash environment, and all of us need the best recipes to get the job done." Keep reading for the rest of Chad's review.

simoniker writes "Over at Dobbs Code Talk, Chris Diggins has been discussing programming languages beyond C++ or Java, suggesting options such as Ruby ('does a great job of showing how powerful a dynamic language can be, and leverages powerful ideas from Smalltalk, Perl, and Lisp') but suggesting Scala as a first choice ('Very accessible to programmers from different backgrounds.') What would your choice be for programmers extending beyond their normal boundaries?"

holy_calamity writes "Researchers have successfully added two 'unnatural' DNA letters to the code of life. They created two artificial base pairs that are treated as normal by an enzyme that replicates and fixes DNA inside cells. This raises the prospect of engineering life forms with genetic code not possible within nature, allowing new kinds of genetic engineering."

Mike Rogers writes "In a move that can only be described as 'Copyright Insanity', Ford Motor Company now claims that they hold the rights to any image of a Ford vehicle, even if it's a picture you took of your own car. The Black Mustang Club wanted to put together a calendar featuring member's cars and print it through CafePress, but an attorney from Ford nixed the project, stating that the calendar pics and 'anything with one of (member's) cars in it infringes on Ford's trademarks which include the use of images of their vehicles.' Does Ford have the right to prevent you from printing images of a car you own?"

deepcleanfun writes "Researchers from New Mexico and Taiwan have invented a tiny probe — about the size of a rice grain — equipped with an ultrasound scanner that can travel through veins and arteries, taking ultrasound images of its surroundings. Unlike previous probes that travel through the body, which provide a view from only one direction at a time, the new device has seven imagers integrated onto the hexagonal prism that can see nearly everywhere at once."

morpheus83 writes "Russian news agency Interfax is reporting that thieves have stolen a three-ton meteorite from the yard of the Tunguska Space Event foundation, whose director said it was the part of meteor that caused a massive explosion in Siberia in 1908. The massive three tonne rock was bought to Krasnoyarsk after an 2004 expedition to the site of the so-called Tunguska event- a mysterious mid air explosion over Siberia in 1908 was 1,000 times more powerful than the nuclear bomb dropped on Hiroshima in 1945. The foundation's director Yury Lavbin claimed to have discovered the wreckage of an alien spacecraft during the expedition."

eldavojohn writes "PhysOrg is covering an interesting year-old paper that proposes an alternative six-dimensional theory of space and time. George Sparling's proposition, based on Einstein's general relativity and Elie Cartan's triality, is a twistor space (which I've only read of in Roger Penrose's latest work). The gist is that space-time is modeled not by four dimensions but by six, and that the extra two dimensions are time-like. Sparling is hoping that tests from the Large Hadron Collider will help prove his theory. The paper is heavy but the PhysOrg article summarizes it nicely."

theodp writes "In a world where nastiness online can erupt and go global overnight, BusinessWeek finds Corporate America woefully unprepared and offers suggestions for how to cope, including shelling out $10,000 to companies like ReputationDefender.com to promote the info you want and suppress the news you don't. And in what must be a sign of the Apocalypse, BW holds Slashdot's moderation system up as a model for maintaining civility in message boards."

necro81 writes "David Pogue of the NY Times has devoted his weekly column to the newly released Apple TV. He also has a video blurb to go with it. He compares it to the XBox360 and Netgear's EVA8000, which also deliver content traditionally trapped in a PC onto a TV set. Apple TV Pros: setup is as easy as can be, it's small and silent form factor will be good for home theaters, and the interface and remote control are intuitive. Cons: HDTV only, playback is limited to formats playable within iTunes, and no internet functionality other than movie trailers."

thefiremonk writes "Bloomberg reports that U.S. District Judge Claude Hilton has issued a permanent injunction against Vonage. The goal: to stop allowing customers to make calls to standard phone lines. 'U.S. District Judge Claude Hilton approved Verizon's request for a block today in Alexandria, Virginia. Hilton said he won't sign the order before a hearing in two weeks on Vonage's request for a stay. A jury found March 8 that Vonage infringed three patents and should pay Verizon $58 million.' Does this spell doom for the already troubled Vonage? "

prostoalex writes "Google's acquisition of online video sharing site YouTube.com resulted in massive traffic headed to uTube.com, "the number one supplier of used Tube & Pipe equipment in the world!", according to the site. CNN Money reports: "The company, which sells used machinery for making tubes to clients worldwide, has seen its site utube.com knocked off line by millions of online searchers looking for video site. "It's killing us," said Ralph Girkins, president and owner of the 22-year-old business. "All my worldwide reps use our Web site. Customers all over the world use it to bring up photos of the machinery, descriptions and specifications there."""
